Grigizial application filed November 16, 190B, Seriai No. 528,272, Divided and this application filed June 5,

191:. Serial No. 631.286.

To all whom it may concern:

e it known that it Amour J. MEIER, citizen of the United States residing at illentlnle. in the county of St. Louis and State of Nis inri huve invented certain new anti-itscfnl [n1 rovenicnts in Concrete Corr struction, (Divisional Case (I) of which the following is u specification.

This application is a division and com (intuition of one tried by me November 16, 1909, Serial 51ov 3 8,272.

'lfhis'invontion relates to certain new and useful improvements in concrete construcmm, and pertains more particularly to a constructirni in which concrete beams and stubs, which torn) the floor and ceiling are sn 'iporteil by uprights or coiumns, and are nni'tml integrnliy together to form av rigid n nit? ry structure.

it is the oi' icct of this invention to pro vi le n conrr'ato structure in which reinforc- (:(l in. and project from. t. l V n J .l beams; and x. 7 I 1 t, the oppositely i! m imrs heir intcgrnliy cor-.ncctcrl or llilttt'ti to irinnontininm ozw piece hers of Jottl'iltfill s; sit the {)(Eli'lifs oi inrnrtnre of the som in the (lr;

to each i bar projecting from the other tenon, mm:

the overlapping'cnds of the bars are Welded or brazed together electrically or in any other tlppltfi'tffl and suitable manner, whcre by the. bars are. united securely together antl form a continuous bar. 10 are embedded in the lower part of each of the beams, and, adjacent the cndsthercof, one or more of said bars 10 turn up wnrdly and project from the beams. The

Reinforcing bars projecting ends of the bars 10, overlap, and

the overlapping bar ends are rigidly secured together by eltling or brazing. Each cutaway portion 6 is covered by a so-callecl form (not shown in the drawings) and the slots and cnt-ni'ay portions are filled with grout. or \vet-c'one.rete, which is'allowctl to therein and unites the beams and the column integrally together.

A flange 11' of each slab 12 rests on a SllOtildBI of A beam 1 and against tenon 4.

The flanges 11 raise the top faces of slabs above shoulder 3, so that when a slab placed upon each shoulder. 3 of a beam 1, u space. 13 above. the tcnon is left, between the two slut ini'orcing bars 1% are. en'tbedded in the slabs and those bars 14, which extend at an angle to space 13, project from each shib into Hitiil space. Each bar '14; projecting supported by the beam. Re- 8 from one of said slabs into space 13 overh PH :1 similar bar 14 projecting from an znljnrent slab, and said overlapping bars are U'I'Qtl together by welding or brazing, whereby the bars are nunle continuous and ether. Grout or wet-concrete 15 is izroti into space l3. and. when it sets r n. unites the slabs and the beams to 1 unitary strinlure,

ions bet ween. the r inforcing obs provide continuous rods ot double thickness, which ux'c 'i n the humus i. Further the re imble thickness which Mei-lie he connections behrecn the- "1 nlcnn-nts are ti nisinot on ly of tiwnnn. 'but in :u'hlition, thc

Finn Utiiitillll, a

the slabs are firmly and securely connected n in above it will be seen that the v i ot the tenons have snnihlr ion riint'orited anti slrcngtlnznctl at "bvre the greatest stresses: exist. 3

pair of beams having their inner; ends resting on'said column, slabs supported on the beams and having their opposite sides adjacent the column arran ed in spaced relation, which space overlies t e column, a series of; reinforcing bars carried by each beam and projecting into said space over the column, the ends of the opposing bars overlapping each other and being integrally connected to form portions of double thickness which overlie the column, and a series of bars carried by the opposing slabs and rojectin in said space over the column, t 'e ends of opposing bars of said slabs overlappin each other and being integrally connected to form portions of double thickness that overlie the column and project in said space thereabove and cross said portions of double thickness of the bars of the beams at points over the column.

2. In concrete construction, a column, a pair of beams having their inner ends resting on the column, a tenon on each beam, shoulders on op osite sides of the tenons of the beams, s abs seating on the shoulders and abutting the tenons and having their top faces'extending overlies. the column,

above the top faces of the beams and providing a space between their opposite 'sides which space a series of reinforcing bars carried by each beam and projecting 'into said space over thecolumn, the ends of the opposing bars overlapping each other and being integrally connected to form portions of double thickness which overlie the column, and a series of bars carried by the opposing slabs and projecting in said 5 ace signature in the presence of two witnesses.
